Watch: Bradley Cooper, Ed Helms, Zack Galifianakis in new 'Hangover 2' trailer
The boys are back in town, and they brought some new pals with them -- including a strong, and strongly amorous, monkey. Bradley Cooper, Ed Helms and Zack Galifianakis return for the Bangkok-set sequel to the 2009 comedy hit. The film also stars newcomers Jamie Chung ("Sucker Punch") and Liam Neeson. Todd Phillips is again directing.
Watch the new full-length trailer above. Best part: Galifianakis referring to the country as "Thigh-land."
"The Hangover Part II" opens nationwide May 26.
